• 2018 Ford F150 Hitch 4-way to 7-way Trailer Connector
  If you need to connect to a trailer that has a 7-way but does not have or need brake signal, 12V power, or a reverse signal then you can the # 337TC1474P connector. It plugs into your existing 4-way and then you can tape the other wires up out of the way. I have included a video of this being installed with another kit on an SUV and at the very end of the video you can see this 7-way being installed. To get a fully functional 7-way on your 2018 Ford F-150 with a factory 4-way, you will...

• Connecting Reverse Lockout Wiring To The Reverse Lights On A 2018 Dodge Durango
  Hi Jason! What you are looking for is something like the Buyers Products Trailer Connector Adapter - 4-Way to 7-Way RV and 4-Way Flat # 337TC1474P. This will piggyback off that Curt T-Connector 4-Flat # C56336 you installed last year, so it will make things somewhat easier. I see what you mean about the location of the reverse lights though. That definitely complicates things. From the way I see it, you have two options. First, you can tie into those reverse lights on the hatch, but it's...

• Recommended Wireless Brake Controller and Wiring for a 2021 Subaru Crosstrek
  Graham, yes you can absolutely use the Curt Echo Wireless Brake Controller # C51180 with your 2021 Subaru Crosstrek. Since you only have a 4-pole though, you are also going to need to add the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation # ETBC7L. This is the preferred kit over the adapter # 337TC1474P because it includes the ring terminals, breaker, zip ties, and screws for install. I've also attached a quick picture that shows you what wires to hook up and where they go.

• Recommended 7-Way Adapter for a Trailer that Has a 7-Way But Doesn't Have Brakes
  Hey Creston. You're going to need the Buyers Products Trailer Connector Adapter item # 337TC1474P. This will plug directly into your 4-way connector. You'll just need to wire in the 12v and ground circuits for a power source to charge your battery. You'll need 12 Gauge Wire item # 12-1-1, which is sold by the foot. You will want to add a 40 Amp In-Line Circuit Breaker item # 9510 in the wire before connecting to the battery. What's your tow vehicle?

• Why Wouldn't Taillight Functions of 4-Way to 7-Way Adapter Work
  Hey Mike, if you are using the Buyers Products 7-Way to 4-Way adapter part # 337TC1474P and none of the trailer lighting circuits are functioning then the issue is related to the 4-way portion of the adapter. I would try pulling the 4-way off and cleaning the pins of both 4-ways and then cleaning them with sandpaper. But if that's is not the fix the issue is related to how the 4-way is powered on the vehicle and you'd need to look at how it installs and fix/address as needed. It could be...

• Recommended 4-Way Wiring Harness for a 2021 Dodge Durango w/out the Tow Package
  Hey David! If you're just wanting to run the lights on that 7-way all you will need is a 4-way harness and a 7-way adapter. This will be a whole lot easier then running the wiring for a 7-way, for functions you have no intention on using. To add a 4-way connector to your 2021 Dodge Durango RT, you will want the Curt T-Connector Vehicle Wiring Harness item # C56336. This custom-fit T-connector plugs into your Durango's wiring harness, which is located behind the tail lights. I have linked...

• Can Connector On Brake Buddy Stealth Be Replaced
  Hi Steve; I can give you the parts for this but I don't recommend it and you may screw up your brake system. I'm with you 100%, the connector on that thing sucks, but they haven't made a way to swap it out. For a standard 7-way you can use # 337TC1474P which comes with a bracket and then the Breakaway Kit # HM39340. If you want my recommendation it would be to sell the Brake Buddy Stealth so you don't have to worry about it and upgrade to a new system like the Curt RVi Series Shadow 2...

• Can I Connect a 7 Way Trailer Plug When My Vehicle Only Has a 4 Way?
  Hi Richard, great question! If your vehicle only has a 4 way flat connector, you can use the Buyers Products Trailer Connector Adapter, part # 337TC1474P, to add a 7 way connector. You will need to ground the white wire to a clean, bare metal surface on the vehicle frame and run the power wire to the battery using 12 gauge wire, part # 12-1-1, with a 40 amp circuit breaker, part # 9510, installed before the battery connection.

• Availability Of Lid Repair Kit For Buyers Products Trailer Connector Adapter 337TC1474P
  Hello Barry, thanks for reaching out. We get asked about this from time to time and I am sorry to say we do not offer a lid repair kit or replacement lid for the 7-way that comes with the # ETBC7L kit. The only solution we can offer for that would be to replace the entire 7-way portion. They are fairly inexpensive and easy to swap out. For that you can use the following: - Buyers Products Trailer Connector Adapter - 4-Way to 7-Way RV and 4-Way Flat # 337TC1474P

• Parts Needed To Add 4-Flat And 7-Way To 2008 Jeep Commander
  Hey Tim, sounds like you are on the right track here. The Tekonsha # 118408 is exactly what you need to add a 4-flat to your 2008 Jeep Commander without the tow package. As far as adding the 7-way, there are two options I want to cover. If you just want to mount a 7-way without running any additional wires, you can use an adapter like part # 337TC1474P. This will plug into the current 4-flat and give you a 4-flat and 7-way combo. Keep in mind this will only be for brake lights, taillights...

• Troubleshooting Pollak Trailer Connector Adapter Not Working With Kioti DK5010 Tractor
  Hi Forrest; because of the way an agricultural 7-way is wired the # PK12-724 is not a good solution. The best thing you can do is run a 7-way blade and connect straight to the trailer. Right now you don't have a brake output pin and it sounds like 12V power is carrying over so the brakes are constantly activated. Also, your tractor will have separate brake light and turn signals which won't work with the Big Tex trailer. To accomplish this you can use the # 337TC1474P along with the #...

• How Does Trickle Charger Connect to Breakaway Battery
  Hey Steve, so the red wire of the Bright Way Trailer Breakaway Unit part # 3802339 is the charge circuit for the battery when connected to a tow vehicle. So you'd want to tap into this circuit to charge it when in storage. So I would run your trick charger to the black wire of the # 337TC1474P and then plug your trailer's 7-way into it and it would charge. Sound feasible?

• Availability of 4-Way to 7-Way Adapter for 2024 Ineos Grenadier
  Hey Brandon, does your 2024 Ineos Grenadier have a 4 way connector on it currently? If so all you'd need to adapt it to a 7-way would be the part # 337TC1474P which your 4-way would plug into and you'd be set. If you have a different trailer wiring connector let me know. If you aren't sure what it's called you can email me a picture of it and I'll be able to ID it.

  Hi James! We can get you squared away, but there are not going to be any plug and play options available for your 2014 Mercedes-Benz GL63 AMG, unfortunately. You will want to start with a 4 flat, like the Tekonsha ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT to get most of the functions working (turn signals, brake lights, and running lights). This doesn't require splicing or cutting into your wires, so it recommended....

• Adding a Charge Line Circuit To a Trailer With a 4-Way/5-Way Flat Connector
  I recommend moving away from the Adapter 4-Pole to 5-Pole Trailer Wiring Adapter # 47515 and going with a Buyers Products Trailer Connector Adapter # 337TC1474P. The wiring and connectors used on the 4-way harness are not designed to be used with the 20amps of power you will putting on the connector. The 4-way/5-way connector cannot handle the additional strain and it will likely overheat with the amperage and risk causing an electrical fire. With the Buyers Products Trailer Connector...

• Parts Needed to Install 7-Way on 2015 Toyota Highlander
  Hey Terry, we can help but we don't have a custom fit 7-way part number that fits your 2015 Toyota Highlander.

We don't have a version with a 5-way on the side but the # 337TC1474P has a 4-way. What are you towing that uses a 5-way?
